Within the same day that reports claimed Shia LaBeouf and his girlfriend, Karolyn Pho, have split, a second report states that Pho's worst nightmare has come true.

Cast members Shia LaBeouf (L) and Carey Mulligan pose during a photocall for the film "Wall Street - Money never sleeps" by U.S. director Oliver Stone during the 63rd Cannes Film Festival in Cannes May 14, 2010.

It was reported on Wednesday that Pho and LaBeouf split following what was nearly a 2-year relationship. The source told Us Magazine that the couple had "split a while ago," and now new sources have confirmed that LaBeouf has been dating in the interim.

The new girl is Mia Goth, whom Pho and LaBeouf had a public fight over in September, after LaBeouf stated that he was going to film "real sex scenes."

"They've been on the rocks ever since Shia agreed to star in Nymphomaniac," a source told Radar Online in a previous interview. "Karolyn doesn't want him having sex with somebody else- simple. She's begged Shia to ask Lars if it's possible to make the scenes appear real, rather than shoot them real."

Now after only a few months, a new source has confirmed that LaBeouf is dating Goth and recently met her parents in London.

"They've kept their relationship under wraps, but they pretty much started dating after he broke off things with Karolyn a few months ago," the source told Radar. "Shia and Karolyn had a volatile relationship and it came to a head just before he began filming Nymphomaniac."

The source suggested that the pair met on the set and LaBeouf was quick to become interested.

"He got to know Mia on set and quickly became enamored of her. They have similar interests, they love alternative music, thrift stores and she is edgy and funny, which Shia loves," the source said. "They're already spending a lot of time together, not just with work, but also have been hitting the town. Mia has made Shia very happy and he's certainly found a party buddy for the time being."
